WINTERIZING Before beginning winterizing, be sure the power is turned off to the water heater. Open all hot water taps on the boat to relieve the pressure and allow cold water to cool the water in the system. Remove both lines from the heater and allow it to drain. After it has drained, blow it out with air pressure, if available. Pour a quart of nontoxic antifreeze (propylene glycol) into the hot water fitting of the tank using a funnel and short length of hose. Be sure power remains off until spring.
2.
Position heater so that electrical cover plates, plumbing nipples and heat exchanger fittings are easily accessible.
3.
Using the four mounting holes provided, securely mount heater to deck or other sturdy flat area. Stainless steel 5/16"(8mm) bolts or lag bolts with flat washers should be used to properly support the strain of a full unit while the boat is rocking.
Raritan 12 and 20 gallon water heaters require auxiliary bracing, when the boat is in heavy seas. This is also recommended for the 6 gallon models if excessive heeling and pitching is expected. See Fig. #3a for optional bracing.
When recommissioning in the spring, run water long enough to insure that all antifreeze has been flushed out and tank is filled BEFORE TURNING ON POWER. Heat exchangers are winterized in conjunction with the boat’s engine cooling system.
PLUMBING CAUTION: To reduce the risk of excessive pressure and temperature in this water heater, temperature and pressure sensitive protective equipment must be installed that meet the requirement of local codes. A device MUST NOT be installed unless it is certified by a nationally recognized testing laboratory and meets the requirements for Relief Valves and Automatic Shut-off Devices for Hot Water Supply Systems, ANSI Z21.11-1979. The relief valve must not be blocked or restricted under any circumstances.
INSTALLATION Materials Required for Installation (not included with water heater): Plumbing: 3/4" NPT "Tee", check valve, expansion tank, drain valve, PTFE tape, vacuum relief valve and shut-off valve. For hot water connections use hose or plastic tubing rated for hot water use. If system will be used with dockside water supply, a pressure regulator valve, set to match boat pressure system is also required. See Fig. #1 for typical installation.
For hot water connections use only pipping, hoses, tubing, fixtures and connectors rated for hot water use.
Electrical: #12-3 stranded cable; circuit breaker (15 amp 120V, 10 amp 240V), wire crimp terminals for #12 wire, and wire supports/straps. For model #17120203 and 17200203 electrical requirements are: #10-3 stranded cable; circuit breaker (both legs simultaneous 20 amp 240V), wire crimp terminals for #10 wire and wire supports/straps.
Avoid sharp bends and 90° ells in the plumbing wherever possible, as they reduce the water flow. Should copper fittings be desired, DO NOT apply direct heat to the 3/4'' nipples protruding from the heater. They contain a nonmetallic lining which will be destroyed by heat. Solder fittings first, then attach to water heater.
Hardware: Four 5/16" (8mm) stainless steel bolts or lag bolts, flat washers and hose clamps. For 12 and 20 gallon models: stainless steel straps and fasteners.
1.
Install Temperature and Pressure Relief Valve in area marked "OPENING FOR TEMPERATURE AND PRESSURE RELIEF DEVICE." Valve is included in box separate from the heater. Use PTFE tape on the threads.
2.
Install a “tee” in the cold water supply line.
Tools needed: Pipe wrench, screw driver, nut driver and wrench(es) for mounting bolts or lag bolts. MOUNTING THE HEATER 1.
Select an area where the heater will not be subjected to water spray (especially salt water).
NOTE: Access or hatch must be large enough for future servicing and/or replacement. L206 0911kgs

3.
From the “tee” run a line to the heater, this line MUST have a vacuum relief valve (such as Watts Model N36) installed to prevent back siphoning which could cause the tank to empty and element to burn out (see Fig. #1). The vacuum break must be mounted higher than the hot water outlet from the water heater.
4.
Connect this cold water supply line to the lower heater connection marked COLD.
5.
Installation of a drain valve between cold water line and heater is recommended (see Fig. #1).
6.
A two gallon expansion tank should be installed in the cold water line to avoid pressure buildup due to thermal expansion of water.
7.
The upper heater connection, marked HOT, is connected to the hot water faucets, shower, etc.
8.
Secure all lines to the boat’s structure at frequent intervals.
9.
Be sure the safety relief valve is connected to hose or piping so that overflow can run unrestricted into the bilge and that a bilge pump is in place. Any discharge from the hose must exit within six inches above or any distance below the structural floor and cannot contact any live electrical part. The relief valve must not be blocked off or reduced in size.
10. For models with heat exchangers see Fig. #4.
WARNING: Before working on unit, be sure that the circuit breaker is off. 1.
Remove access panel.
2.
Strip outer insulation off the cable (long enough for green ground wire to reach Grounding Screw) exposing three insulated wires.
3.
Loosen strain relief connector by turning counterclockwise and insert cable. Then expose approximately 5/16" (8mm) of bare wire on each of the three pieces of stranded wire.
4. Grounding: Join the AC Grounding Conductor (green), using the crimp-on terminal end (provided), to the screw at the bottom of the Thermostat Bracket. 5.
Attach black and white wires to Thermostat per Fig. #2. Use crimp-on terminal ends (provided) to ensure a secure installation. Do not use solder as it will cause the wire to become solid rather than stranded (making it susceptible to breakage due to vibration).
6.
Tighten strain relief by turning it clockwise.
Fig. #2
ELECTRICAL PREPARATION All wiring should be done in accordance with ABYC E8, AC wiring standard. 1.
Install a 15 amp (10 amp for 240V AC or 20 amp for model #17120203 and 17200203) Circuit Breaker in the 120V AC service line to the water heater.
2.
Use ONLY STRANDED #12-3 (#10-3 for model #17120203 and 17200203) cable to the heater. NEVER use solid (ROMEX-type) wire on a boat; vessel vibration causes breakage due to metal fatigue (see U.S. Coast Guard CFR Title 33, Part 183.423).
3.
WIRING
Secure wire at intervals of 18" (45.7cm). Allow about 24'' (61cm) of extra wire to make necessary connections.

START - UP WARNING: Be sure power to water heater is off during start-up. 1.
After all plumbing lines have been properly installed and secured, open the hot water taps and turn on the water pressure system.
2. Allow water to run a few minutes to expel air from water heater and lines. Failure to expel air may cause an air pocket in the tank. This will cause the heating element to burn out, as it will not be in contact with water. All the air may not be expelled after purge, however over a period of time (two weeks) the remaining air in the tank will be absorbed by the water. 3.
Check for leaks.
